SASH-FASTENER.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed June 3, 1909. Serial No. 499,881.

To all whom it may concern:

Be it known that I, EMMA L. BRENNER, a citizen of the United States,residing at Milwaukee, Milwaukee county, Wisconsin, have inventedcertain new and useful Improvements in Sash-Fasteners; and I do herebydeclare the following to be a full, clear and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to certain improvements in sash fasteners, andmore particularly relates to combined window and sash fasteners; and theobjects and nature of my invention will be readily understood by thoseskilled in the art in the light of the following description of theaccompanying drawings illustrating what I now consider my improvedembodiment from among other formations and arrangements within thespirit and scope of my invention.

An object of the invention is to provide an improved lock adapted tofasten together both the lower and upper sashes of a window againstvertical movement and whereby the lower sash can be held locked againstraising while the upper sash can be released for vertical movement, andwhereby the sashes can be locked together in various vertical positionswith either or both sashes partially opened.

A further object of the invention is to provide certain improvements information, arrangement and combinations of parts whereby a highlyeflicient and advantageous sash and window lock will be produced.

The invention consists in certain novel features in construction,arrangements and combinations of parts as more fully and particularlyset forth hereinafter.

Referring to the accompanying drawingsz-Figure l, is a perspective viewof the meeting portions of the upper and lower sashes of a window andthe adjacent frame, showing a lock of my invention applied thereto. Fig.2, is a horizontal sectional view. Fig. 3, is a detail top plan of thelock, dotted lines indicating hidden parts.

In the drawings, a, is the lower sash of a window having the top rail 6,and c, is the upper sash of the window; d, is an elongated metal platearranged vertically of and secured to the window frame adjacent to thelower sash so that said sash will move longitudinally of said plate whenbeing raised.

This plate is formed with a vertical series of spaced openings orsockets d.

e, is an elongated metal plate arranged vertically and secured to avertical rail of the upper sash c, and formed or provided with avertical series of spaced openings or sockets e.

The lock mechanism of my invention is adapted to be fixed on the toprail of the lower sash adjacent to the vertical plates (Z, c, and isprovided with bolts toenter the sockets or openings of said plates,respectively, to lock the lower sash to the frame and the upper sash tothe lower saslr' The lock mechanism comprises a suitable strong metalcasing f, usually flat and of any suitable shape or form and adapted tofit horizontally on the top face of the lower sash top-rail and herigidly secured thereto by screws 2, or the like. The casing is formedusually near one end with a transverse bolt slide or guide-way 7,opening through to the edge thereof adjacent the upper sash to receivebolt 9, for locking the upper sash to the lower sash. At the outercorner of the inner end of said casing, that is, at the same end asguide-way the casing is provided with a longitudinally arranged slide orguide way 7 projecting longitudinally beyond the casing end and open atits outer end to receive the longitudinally movable bolt h, for lockingthe lower sash to the window frame. The bolt slideways f, f, at theirinner portions open into the interior of the casing, and said slidewaysare usually arranged at the same end of the casing and about at rightangles to each other. A lever 2', is arranged longitudinally of andwithin the casing and about midway its length is fulcrumed thereon avertical pin or axis j. At one end this lever extends transversely ofthe inner end of the bolt 9, and is coupled thereto to project andwithdraw the same through the medium of pin 9, rigid with the bolt endand confined in slot 2', formed longitudinally in the lever end. A plateor other suitable spring is is arranged and secured in the casing withits free end bearing against the free end of lever c, and constantlyexerting its tension to swing said lever in a direction to hold the bolt9 projected. The free end of lever z is preferably provided with anoperating finger-piece, knob or handle 2'", arranged at the exterior ofthe casing top-plate with its shank or post secured to the lever end andpassing vertically through curved or segmental slot Z, in the casingcover or topplate, whereby the bolt 9, can be operated from the exteriorof the casing by moving the knob i, longitudinally of the slot Z, andthe bolt can be held withdrawn against the tension of spring 70, bypressing the shank of knob 71 into the offset or recess Z at the inneror right hand end of slot Z, and on moving or springing the knob shankfrom.

said recess, the spring 70, will return the bolt to projected or lockingposition. The bolt it, can be operated from the exterior of the casingthrough the medium of finger piece, knob or handle it, at the exteriorof the casing and secured to the inner end of said bolt by a verticalpin or shank h, passing through elongated slot m, in and longitudinallyof the casing top-plate. The pivot j, can pass through longitudinal slotj, in lever 2', to permit longitudinal movement of the lever to carrythe shank 2', into or from the locking notch or offset Z, as will beunderstood by those skilled in the art.

I provide means wherebythe bolts h, 9, can be operatively connected tooperate in unison, that is, whereby the bolts can be withdrawn or can beprojected simultaneously, and in the particular example illustrated,such means is arranged to operate the bolt g, to perform its withdrawingstroke by or from the bolt h, when moved on its withdrawing stroke, andto actuate the bolt h on its projecting stroke by the movement of thelever 2', when projecting the bolt 9. In the example shown, ahorizontally swingable lever n, is arranged within the casing, andmounted to swing on vertical pin or fulcrum 0, to form the operativeconnection between bolt 72,, and lever '5. One end of the lever 42., isconnected to the inner end of the bolt h, by the knob shank h, passingloosely through elongated slot n, in said lever end,

so that the lever will swing as the bolt h, reciprocates. The lever 02.is of angular or approximate bell-crank formation with its fulcrum 0,arranged at the apex of the angle and its outer arm extending outwardlyand laterally at an inclination from the fulcrum to the bolt h, whilethe inner or free end of the lever extends inwardly beside orlongitudinally of the free end of lever 2', and is formed with alongitudinally curved cam or bearing face 12.", against which the freeend of the lever 2' is yieldingly held by spring 10, in a direction toproject bolt g and to rock the angle lever 'n, to project the bolt h.When the bolt h is withdrawn by its knob 71/,

0 the slotted end of lever 10. is swung inwardly or to the right and thebearing-surface end of said lever is swung laterally against lever 71,and lever 75 is thereby swung against the tension of the spring and in adirection to 5 withdraw bolt 9', and the bolts h, g, will thus besimultaneously withdrawn from the plates (Z, c, and both window sasheswill be released for raising or lowering. When the operating knob orhandle of bolt 72., is moved in the opposite direction so as to releasethe parts, the spring is will propel the lever c' in bolt-projectingdirection and through the medium of lever 71 will simultaneously projectlever n, in bolt projecting direction. The bolt h, enters the holes or75' sockets of plate (Z, to lock the lower sash t0- the frame, and thebolt enters the holes of plate 0, to lock the upper sash againstmovement, but bolt 6, can be withdrawn in the manner liereinbeforedescribed, indes0 p-endently of bolt 71., to release the upper sash forvertical movement while the lower sash remains locked to the frame.

It 1s evident that varlous changes and modifications might be resortedto in the 5" forms, constructions, and arrangements of the partsdescribed without departing from the spirit and scope of my invention,hence I do not wish to limit myself to the exact constructionsdisclosed. on
